[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0043] The following describes the sound field adjustment method, device, vehicle and storage medium of the vehicle of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the related technology mentioned in the above background technology center cuts off the multimedia audio while playing the navigation audio or communication audio, and the sound field adjustment parameters do not reach the optimal conditions, the driver's audio needs are met at this time, but the passenger's audio needs cannot be met, so that the driver and the passenger's needs cannot be met at the same time, the present application provides a sound field adjustment method for a vehicle, in which the playback mode of the vehicle-mounted multimedia can be optimally controlled based on the optimal sound field adjustment parameters, the different audio needs of different users can be met, the driver's playback needs can be met while the passenger's playback needs can be met, the driving experience of the vehicle can be improved, and the practicality of the vehicle can be effectively guaranteed. Thus, the problem that the related technology cuts off the multimedia audio while playing the navigation audio or communication audio, and the sound field adjustment parameters do not reach the optimal conditions, the driver's audio needs can be met at this time, but the passenger's audio needs can not be met, so that the driver and the passenger's needs cannot be met at the same time.

[0044] Specifically, Figure 1 A schematic flow chart of a method for adjusting the sound field of a vehicle provided in an embodiment of the present application.

[0045] like Figure 1 As shown, the vehicle sound field adjustment method includes the following steps:

[0046] In step S101, it is determined whether there are passengers in the current vehicle.

[0047] During the actual implementation process, the embodiment of the present application can first determine whether there are passengers in the current vehicle, such as through the passenger monitoring system in the vehicle, the status of the seat belts in the vehicle, the status of the door switch, etc., to determine whether there are passengers in other positions besides the driving position.

[0048] For example, an embodiment of the present application can collect in-vehicle images through the camera of the passenger monitoring system, extract passenger features from the in-vehicle images, and determine whether there are passengers in the current vehicle; for another example, an embodiment of the present application can determine whether there are passengers in the vehicle by the usage status of the in-vehicle seat belts at each position, that is, when the seat belt at a certain position is in use, it indicates that there is a passenger at this position, that is, there are passengers in the car, and when the seat belt at a certain position is not in use, it indicates that there is no passenger at this position, that is, there are no passengers in the car; for another example, an embodiment of the present application can determine whether there are passengers on the vehicle by the door switch status, such as when it is identified that a door is opened and closed, it is determined that there are passengers in the vehicle, and when it is identified that all doors except the main driving door are always closed and not opened, it is determined that there are no passengers in the vehicle.

[0049] The embodiment of the present application can determine whether there are passengers in the current vehicle by combining one or more recognition methods, so that when there are passengers in the vehicle, there are different audio needs of the driver and the passengers. Otherwise, there are no different audio needs of the driver and the passengers, and no parameter adjustment is required.

[0050] In step S102, if there are passengers in the current vehicle and the current vehicle is in the navigation broadcast mode, the passenger distribution positions of the current vehicle are identified.

[0051] It can be understood that based on the event signal emitted during the navigation voice broadcast, it is determined that the vehicle is in the navigation broadcast mode, and when the navigation broadcast occurs and ends, the signal can be transmitted to the main control module. In the navigation broadcast mode, it indicates that there are different audio needs of the driver and the passengers. Therefore, the embodiment of the present application identifies the passenger distribution position and can more accurately match the optimal adjustment parameters according to the passenger distribution position.

[0052] For example, the embodiment of the present application can identify the distribution position of passengers in the current vehicle through a camera that collects images in the vehicle, a pressure sensor set under each seat, etc. For example, the embodiment of the present application can collect images of passengers in the vehicle through a camera, and determine the specific position of the passengers based on the images of passengers in the vehicle; for another example, the embodiment of the present application can sense the pressure signal on each seat through a pressure sensor, and determine the specific position of the passengers based on the pressure signal on each seat.

[0053] When there are passengers in the vehicle and the vehicle is in navigation mode, the embodiment of the present application can adjust parameters by identifying the distribution positions of the passengers in the current vehicle, thereby improving the accuracy and reliability of the sound field adjustment.

[0054] In step S103, the optimal sound field adjustment parameters of the current vehicle are matched according to the passenger distribution positions, and the playback device at the main driver's position and / or the playback device at the passenger position of the in-vehicle multimedia is adjusted according to the optimal sound field adjustment parameters, so that the navigation audio or call audio can be played to the driver while the multimedia audio is played to the passengers.

[0055] It is understandable that the adjustment parameters of the sound field can affect the sound effects of the audio system, and thus affect the auditory experience of the passengers. The embodiment of the present application can match the optimal sound field adjustment parameters of the current vehicle according to the passenger distribution position, and adjust the playback device at the main driver's position and / or the playback device at the passenger position of the vehicle-mounted multimedia according to the optimal sound field adjustment parameters, so that the audio system plays multimedia audio to the passengers while playing navigation audio or call audio to the driver.

[0056] Specifically, after determining the distribution positions of passengers in the vehicle, the embodiment of the present application can match the optimal sound field adjustment parameters of the current vehicle according to the distribution positions of the passengers, and adjust the playback device at the main driving position and / or the playback device at the passenger position of the vehicle-mounted multimedia according to the optimal sound field adjustment parameters. For example, when there are passengers in the vehicle and the vehicle is in the state of navigation broadcast, the sound field adjustment parameters of the front left (main driving position) can be adjusted, and the navigation broadcast volume can be appropriately increased to ensure that the driver can hear the navigation sound clearly, while not cutting off the multimedia audio, to meet the playback needs of the passengers.

[0057] The sound field is set according to the specific position of the passengers. While playing multimedia audio to the passengers, navigation audio or call audio is played to the driver. This meets the playback needs of the driver while meeting the playback needs of the passengers, improving the driving experience of the vehicle and effectively ensuring the practicality of the vehicle.

[0058] Optionally, in an embodiment of the present application, the optimal sound field adjustment parameter includes at least one of a switch, volume, timbre of a speaker of the playback device and a position, width, and depth of the sound field.

[0059] It can be understood that the speaker switch of the vehicle-mounted multimedia playback device in the embodiment of the present application can control the turning on and off of the vehicle-mounted multimedia sound, the volume and timbre can affect the passengers' auditory experience, the position of the sound field can include the front, rear, high and low of the sound field, and the vehicle sound field setting usually has four directions, namely front left (driver's seat), front right (passenger seat), rear left (the seat behind the rear driver's seat), and rear right (the seat behind the rear passenger seat).

[0060] Specifically, the embodiments of the present application can adjust the optimal sound field adjustment parameters by adjusting the switch, volume, timbre of the speaker of the vehicle-mounted multimedia playback device and at least one of the position, width and depth of the sound field. For example, during navigation broadcasting, the embodiments of the present application can turn on the speaker of the front left (main driver's seat) sound field, increase the volume of the navigation, and appropriately lower the volume of the multimedia audio to ensure that the driver can hear the navigation content clearly without cutting off the multimedia audio, thereby meeting the different audio needs of the driver and passengers; for another example, the embodiments of the present application can adjust the timbre of the navigation and multimedia audio during navigation broadcasting mode to ensure the clarity of the sound and improve the auditory experience of the passengers; for another example, the embodiments of the present application can adjust at least one of the position, width and depth of the sound field to change the sound effect of the navigation audio or multimedia audio.

[0061] The embodiments of the present application can meet the different audio needs of different users by adjusting the optimal sound field adjustment parameters, improve the continuity and purity of the passengers' auditory experience, and improve the driving experience of the vehicle. The optimal sound field adjustment parameters can include many types, which are not specifically limited here.

[0062] Optionally, in one embodiment of the present application, before matching the optimal sound field adjustment parameters of the current vehicle, it also includes: detecting whether the current vehicle meets preset sound field adjustment conditions; when it is detected that the preset sound field adjustment conditions are met, controlling the current vehicle to enter a sound field adjustment mode, otherwise no sound field adjustment is performed.

[0063] In one embodiment of the present application, the preset sound field adjustment condition includes that the sound field adjustment switch of the current vehicle is in an on state.

[0064] It is understandable that in the embodiment of the present application, the vehicle meeting the preset sound field adjustment condition may include but is not limited to the vehicle turning on the sound field adjustment function. If the sound field adjustment switch is in the on state, it is determined to turn on the sound field adjustment function, thereby determining whether the current vehicle meets the preset sound field adjustment condition. It should be noted that the preset sound field adjustment condition can be set by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0065] The embodiment of the present application can control the vehicle to enter a sound field adjustment mode based on satisfying preset sound field adjustment conditions, and match the optimal adjustment parameters of the vehicle, thereby meeting the different audio needs of the driver and passengers.

[0066] Optionally, in one embodiment of the present application, the preset sound field adjustment condition includes that a sound field adjustment switch of the current vehicle is in an on state.

[0067] It can be understood that the sound field adjustment switch in the embodiment of the present application can control the sound field function to be turned on and off, thereby controlling the current vehicle to enter or exit the sound field adjustment mode. When the sound field adjustment switch of the vehicle is turned off, it is determined that the preset sound field adjustment conditions are not met, and the vehicle does not perform sound field adjustment.

[0068] Optionally, in one embodiment of the present application, it is determined whether the navigation audio or the call audio has been broadcasted to the end; if the navigation audio or the call audio has been broadcasted to the end, the optimal sound field adjustment parameters of the in-vehicle multimedia are adjusted back to the initial sound field adjustment parameters to continue playing the multimedia audio to the driver.

[0069] It is understandable that the initial sound field adjustment parameters may represent parameters before being adjusted to the optimal sound field adjustment parameters, or may represent parameters preset by the user, which is not specifically limited herein.

[0070] As a possible implementation method, the embodiment of the present application can obtain the navigation audio or call audio end signal of the current vehicle through the main control module. When the navigation broadcast ends, the navigation broadcast end signal is transmitted to the main control module. The main control module can adjust the optimal sound field adjustment parameters of the vehicle-mounted multimedia back to the initial sound field adjustment parameters based on the navigation broadcast end signal, so that the sound field settings are restored to the settings before the settings, so that the multimedia audio can continue to be played to the driver, thereby improving the continuity of the auditory experience.

[0071] For example, when there are drivers and passengers in the car and the vehicle is not in navigation broadcast mode, the in-car multimedia can play audio to meet the needs of the driver and passengers to listen to music. When the vehicle enters the navigation broadcast mode and navigation broadcast is required, the optimal sound field adjustment parameters can be matched according to the passenger position. The speaker switch can be turned on, the navigation volume can be appropriately increased, and the sound field position can be adjusted to the front left (main driver's seat) to ensure that the driver can hear the navigation sound clearly for safe driving. At the same time, the multimedia volume can be appropriately lowered without cutting off the multimedia audio to meet the passengers' playback needs. When there are drivers and passengers in the car and the navigation broadcast mode ends, the speaker can be turned off and the volume of the in-car multimedia can be adjusted back to the original volume to continue playing multimedia audio to the driver, meet the driver's playback needs, improve the vehicle's driving experience, and ensure the practicality of the vehicle.

[0072] Optionally, in one embodiment of the present application, after matching the optimal sound field adjustment parameters of the current vehicle, the method further includes: collecting the identity of the driver; and correcting the optimal sound field adjustment parameters according to the identity.

[0073] It can be understood that the embodiments of the present application can collect the driver's identity through facial recognition to obtain the driver's identity information, including but not limited to the driver's age, identity, preferences, etc. The optimal sound field adjustment parameters can be corrected according to the driver's identity, effectively improving the user experience.

[0074] For example, the embodiment of the present application can capture facial images through a facial recognition camera and identify facial image information. When the driver is identified as being 60 years old, the volume of the navigation broadcast can be increased during the navigation broadcast so that the driver can hear the navigation sound clearly, ensure safe driving of the vehicle, and meet the driver's broadcast needs. When the driver is identified as being 25 years old, the volume of the navigation broadcast can be kept consistent with that of the multimedia playback. For another example, when the facial recognition camera captures a facial image and recognizes that the driver has played light music many times in the past, the volume of the multimedia playback can be lowered by analyzing the driver's preferences, and soothing slow-tempo songs can be recommended to meet the driver's playback needs.

[0075] The embodiment of the present application can identify the driver's identity and correct the optimal adjustment parameters. It can adjust the speaker's switch, volume, timbre and at least one of the position, width and depth of the sound field, so as to meet the driver's playback needs and further improve the driver's auditory experience.

[0076] Optionally, in one embodiment of the present application, after matching the optimal sound field adjustment parameters of the current vehicle, it also includes: extracting audio content of the navigation audio or call audio; and correcting the optimal sound field adjustment parameters based on the audio content.

[0077] It is understandable that when the audio content of navigation audio or call audio involves privacy, the embodiments of the present application can correct the optimal sound field adjustment parameters based on the audio content, such as turning off the speaker switch of the in-vehicle multimedia playback device, lowering the volume of the in-vehicle multimedia playback, etc.

[0078] For example, the embodiment of the present application can extract the audio content of the call audio when the driver is making a voice call. When it is recognized that the audio content involves sensitive words or privacy, the front left (main driver's seat) sound field adjustment parameters can be adjusted to automatically lower the volume of the voice call, thereby protecting the privacy and safety of the driver and passengers and improving the driving experience of the vehicle.

[0079] Specifically, combined Figure 2 and Figure 3 As shown, the working principle of the vehicle sound field adjustment method of the embodiment of the present application is described in detail with an embodiment.

[0080] like Figure 2 As shown, the embodiment of the present application may include the following steps:

[0081] Step S201: Determine whether there are passengers in the current vehicle. The embodiment of the present application can determine whether there are passengers in the current vehicle through the passenger monitoring system in the vehicle, the status of the seat belt in the vehicle, the status of the door switch, etc.

[0082] For example, an embodiment of the present application can collect in-vehicle images through the camera of the passenger monitoring system, extract passenger features from the in-vehicle images, and determine whether there are passengers in the current vehicle; for another example, an embodiment of the present application can determine whether there are passengers in the vehicle by the usage status of the in-vehicle seat belts at each position, that is, when the seat belt at a certain position is in use, it indicates that there is a passenger at this position, that is, there are passengers in the car, and when the seat belt at a certain position is not in use, it indicates that there is no passenger at this position, that is, there are no passengers in the car; for another example, an embodiment of the present application can determine whether there are passengers on the vehicle by the door switch status, such as when it is identified that a door is opened and closed, it is determined that there are passengers in the vehicle, and when it is identified that all doors except the main driving door are always closed and not opened, it is determined that there are no passengers in the vehicle.

[0083] The embodiment of the present application can determine whether there are passengers in the current vehicle by combining one or more recognition methods, so that when there are passengers in the vehicle, there are different audio needs of the driver and the passengers. Otherwise, there are no different audio needs of the driver and the passengers, and no parameter adjustment is required.

[0084] Step S202: Determine whether the vehicle is currently in navigation broadcast mode. As a possible implementation method, it can be determined that the vehicle is in navigation broadcast mode based on an event signal issued during navigation voice broadcast.

[0085] Specifically, the embodiment of the present application can determine whether the current vehicle is in the navigation broadcast mode, and an event signal can be issued during the navigation voice broadcast. When the navigation broadcast occurs and ends, the input signal can be transmitted to the main control module. The main control module can obtain the data of the passengers and the navigation broadcast, so as to determine whether the current vehicle is in the navigation broadcast state. In the navigation broadcast mode, the passenger distribution position can be identified, and the optimal adjustment parameters can be matched more accurately.

[0086] Step S203: Setting the vehicle sound field settings according to the preset adjustment parameters. In the embodiment of the present application, the vehicle sound field settings can be set by judging the navigation broadcast status in step S202.

[0087] In the actual implementation process, the embodiment of the present application can identify the passenger distribution position of the current vehicle when there are passengers in the vehicle and the vehicle is in the navigation broadcast mode, match the optimal sound field adjustment parameters according to the passenger distribution position, and adjust the playback device at the passenger position of the in-vehicle multimedia according to the matched optimal sound field adjustment parameters. For example, Figure 3 As shown, when the vehicle is driving normally, the front left (main driver's seat) and front right (passenger driver's seat) of the vehicle can both broadcast multimedia audio. When the vehicle is in the navigation broadcast state, the optimal sound field adjustment parameters can be matched according to the passenger distribution position, and the on-board multimedia playback device can be optimally controlled based on the optimal adjustment parameters. The volume of the front left (main driver's seat) can be appropriately increased, and the speaker of the front left (main driver's seat) can be turned on to ensure that the driver can hear the navigation voice clearly and ensure the safety and convenience of vehicle driving. After the navigation voice broadcast is finished, the optimal sound field adjustment parameters of the front left (main driver's seat) can be adjusted back to the initial sound field adjustment parameters to meet the driver's audio needs, improve the vehicle's driving experience, and effectively ensure the practicality of the vehicle.

[0088] Step S204: Determine whether the current navigation broadcast is completed.

[0089] In an embodiment of the present application, after the navigation broadcast is completed, a return end signal can be transmitted to the main control module, and the navigation broadcast is ended at this time. If the main control module does not receive the return end signal, the navigation broadcast is not ended at this time. By judging whether the navigation broadcast is currently completed, the vehicle sound field setting can be further performed.

[0090] Step S205: After the announcement is completed, the previous vehicle sound field setting is restored.

[0091] Specifically, the vehicle main control module in the embodiment of the present application can obtain the data of passengers and navigation broadcasts, and according to the signal of the end of the navigation broadcast, restore the sound field settings to the settings before the settings, and adjust the optimal sound field adjustment parameters back to the initial sound field adjustment parameters. Through active adaptive sound field settings, the manual sound field settings that are time-consuming and labor-intensive to a certain extent are simplified, which saves time and effort and increases the good experience of passengers.
